Wobbe-Index, Air demand, Density and Calorific value of gaseous fuels are the measuring values required for steady and energy efficient control of a burner or the control of a gas mixing station for precisecompliance with contract values at the transfer point. 

For these applications AMS offers two measuring systems which distinguish themselves by the different measuring principle: The RHADOX^TM series for the measurement of Wobbe-Index and Air demand in process off-gases and the FT-TC series for the constant control of density and calorific value of gas mixing station.
